Bricked? Powercolor 5850 after bios flash

Hi Guys,
I have some Kind of a strange Problem with my Powercolor 5850 Radeon 1Gb.

Had the Dual Monitor flicker issue and decided to RBE-modify the clock table.
So I flashed this modded bios; no success flickering remained.
Tried multiple clock and voltage settings flashed them (also using ATIflash 3.99)
Nope, issue remains the same-.-

So now comes the weird thing:
I sucessfully tried the EEPROM trick and was able to reflash the original bios.
BUT!
The card is recognized as Standard-VGA Adapter.
GPU-Z and HWinfo64 gives me a Core clock value of 13,6 MHz and a memory clock of 3196MHz.
Also the Memory Interface Width is read out with a 512 Bits oO?

So installing the proper VGA Driver ends up with a Black screen (while using the GeForce 8200 onboard VGA).

I already tried flashin the bios with different bios versions from the TPU-DB, also tried several flash options (like -newbios, -f, -fa)

Any Help please? I'm sure I hadn't fried anything while soldering the bridge over the eeprom.

My Sys-Specs:

Main Sys (which is home of the 5850, and I also used for the first flashing attempts)

**If you are able to access windows with a spare vga card or on-board vga; Uninstall and deep clean any AMD drivers for the vga card before the flash process**

Use bootable flash drive with atiflash and original vbios image

Type at the dos prompt - dir to view the content of the flash drive

Type at the dos prompt; atiflash -ai 0 [see if adapter is at this address and is recognised]

Re-flash the original or Backup/copy of the original vbios image
Type at the dos prompt; atiflash -f -p 0 [VBiosName].rom

[Note: 0 is the primary card PCIe slot one & 1 is the secondary PCIe slot two]
[Note: when booting from on-board vga / igp also = primary position 0]

Hi Law-II,
already did that a couple of times but I don't even get a POST screen with the 5850. That's what bothers me
Also after having tried several different bioses (which are all correctly recognized by GPU-Z) I still have no video AND if I reinstall drivers (jupp I did use the removal tool and even tried a newly set up system) I get a black screen even from the onboard VGA.

Would double check the solder points, make sure the PCB trace is not in contact with any wire or old solder on or *near to pin1 & pin8

Note: no vga from on-board vga /iGP would suggest dead hardware has been placed in a PCI/PCIe slot [*may be due to a short on the 5850] assuming that the on-board vga /iGP works once the 5850 is removed.

Also Note: EEPROM cannot sustain flashing and that it can only be flashed a certain number of times before failing [although I have not had this happen; its not to say it dose not occur from time to time]

No No you got me wrong!
The system works fine even with the 5850 installed as long as it operates as a generic vga device.
Installing Radeon Drivers causes the the IGP graphics to black out.
I will take it apart... hopefully I'll find something

If youve tried this but the same thing still happens then id say you've installed the wrong bios on your 5850... Sometimes cards are identical - same manufacturers code & partnumber etc etc but one bios wont work with the other because the revision of 1 card is different from the other

solder two leads onto the pins you shorted before and wired that up to a toggle switch make sure the switch is OFF when you power the machine on once you are booted to a atiflash prompt turn the switch on complete the flash and then turn it OFF again before doing a reboot
